The evolution of DDT resistance and the harm both to humans and the environment led many governments to curtail DDT use.[13]

DDT cannot be used to control bed bugs. Because DDT was once used this way, some people have suggested that bringing back DDT could solve bed bug problems today. This is not true. Although the insecticide DDT helped to get rid of bed bugs in the 1950s, it is not effective to use today and has risks. By the 1950s, many populations of bed bugs around the world were resistant to DDT.1 In 1956 pest control specialists started recommending that people stop using DDT for bed bugs and use different insecticides instead.1 DDT was banned in the United States in 1972 for health and environmental reasons.2

滴滴涕（英語：DDT），全名雙對氯苯基三氯乙烷（英語：Dichloro-Diphenyl-Trichloroethane），化學式為(ClC6H4)2CH(CCl3)。白色晶體，不溶於水，溶於煤油，可製成乳劑，對人類毒性高[3]，曾經是最著名的合成農藥和殺蟲劑。後來人們發現滴滴涕不易降解，積累下來對魚類和鳥類生存繁殖不利，破壞生態平衡，在世界大部分地區已經停止使用滴滴涕，只有少數地區還繼續使用以對抗瘧疾。世界衞生組織WHO界定為二級致癌物。

After DDT was banned, people started using pyrethroid pesticides, like deltamethrin and lambda-cyhalothrin, for bed bugs.1 Pyrethroids kill insects in a similar way as DDT. Both pyrethroids and DDT target the same part of an insect's nervous system.1,7 Because of this, some bed bugs that were resistant to DDT were also resistant to pyrethroids, even if they had never been around pyrethroids before. This is called cross-resistance.3,6,7
Some experts believe that cross-resistance is one of the reasons why bed bug populations have increased recently.1,3 Another reason why bed bugs are increasing could be that people today are less aware of how to avoid spreading bed bugs and because people travel often between different cities and countries.4
Recent tests show that many bed bugs are still resistant to DDT, years after DDT was banned.3,7 This may be because of cross-resistance between DDT and other pesticides. Scientists studying bed bug resistance to insecticides in 2010 found that almost 90 percent of bed bugs across the United States had a mutation that would help them survive the use of insecticides like DDT and pyrethroids.7

But going back to old pesticides won’t fix it, particularly DDT, said Roger Burley, president of Aanteater Pest Control in Hamilton. Bed bugs are resistant to DDT and most other pesticides that used to treat it.
“DDT is really dangerous, and it’s really not effective against bed bugs anyway,” he said.
“I’d love to have a silver bullet that would wipe them right out, but it’s not DDT.”

“DDT is really dangerous, and it’s really not effective against bed bugs anyway,” he said.
“I’d love to have a silver bullet that would wipe them right out, but it’s not DDT.”
But every chemical that used to kill bed bugs wouldn’t work anymore, Burley said. It wasn’t DDT that took them to near extinction, but a chemical complex called organophosphates. And bed bugs are immune to that too now, he said.
“Every 10 years, we have to find something new to kill them,” he said.
“They’ve mutated so much. The chemicals we use now are not even related to those chemicals, and we’re actually having some success.”
DDT was a widely used pesticide until about 40 years ago. The federal government banned it because of its impact on wildlife, particularly bird populations.
'We're fighting a pretty good fight'
Little research appears to exist on the toxicology of DDT in limited doses, indoors, to combat bed bugs. American organizations such as the Public Health Institute have come out against its use to combat malaria in third-world countries.
The current chemicals are working, Burley said. The bed bug population has exploded in Hamilton, but anecdotally, it seems to be leveling off, he said. Modern defecants can kill them in 24 hours.
“We’re fighting a pretty good fight,” he said.
Bed bugs aren’t as resistant as they once were because of the pesticides humans have thrown at them, he said. “They’re getting weaker and weaker.”
But “DDT is going to have zero effect. All it’s going to do is a lot of damage.”

恐怖過五毛蟲
之前屋企都有
蒸氣work?
有無床蝨概念股
講真，支那藥真係勁試過成屋螞蟻，試左勁多藥都唔得
買左咗隻中國出既炸蟻粉
落咗次，成屋蟻唔見哂香港本身有部分屋企都有啦
係睇有冇特別品種同有冇傳到出街
香港巴士，小巴，的士，地鐵櫈應該都養唔到
ikea 可以一戰

要用個d蒸機
要物理整死
高溫
或者用DE粉物理整死啲幼蟲

床蝨本來是酷刑工具
.........20世紀讓人聞之膽寒的刑訊手段。如果說前面的刑罰手段是以殘酷、血腥震懾犯人，那麼臭蟲室則是憑藉噁心而位列克格勃酷刑之首。是的，無比的噁心……
受過大量刑訊手段但仍未招供的犯人會被脫光全身的衣物，帶到臭蟲隔離室。隨後特工啟動機關，將飼養的成千上萬的臭蟲放進隔離室。天花板、牆上、地上、空中……噁心的臭蟲佔據了狹小密閉空間。不久後，臭蟲開始爬滿受刑者的身體，他們叮咬摧殘著犯人身體的每一寸肌膚，吸食他的血液……本就已經遍體鱗傷甚至奄奄一息的犯人幾乎沒人能活著走出這間地獄……

De粉要長時期先消滅到。一遇床蟊基本上同裝修間屋無分別
支那農藥/殺蟲不嬲勁，可以連人都死埋
